If you have trouble using the touchscreen or Home button, use Touch Accommodations to change how your device responds to your touch.
Choose how long you must touch the screen before a touch is recognized. You can configure iPod touch to respond only to touches of a certain duration. Go to Settings > General > Accessibility > Touch Accommodations, turn on Hold Duration, then use the Gesture Delay plus and minus buttons to choose a duration (the default is 0.10 seconds).
Choose the duration in which multiple touches are treated as a single touch. If you have trouble touching the screen just once, turn on Ignore Repeat. Then, if you touch the screen several times quickly, iPod touch treats the touches as one. To change the amount of time between touches before iPod touch treats them as one, go to Settings > General > Accessibility > Touch Accommodations, turn on Ignore Repeat, then use the Gesture Delay plus and minus buttons to adjust the timing.
Choose the location where iPod touch responds to the first or the last place you touch. Go to Settings > General > Accessibility > Touch Accommodations, then choose a Tap Assistance option (Use Initial Touch Location or Use Final Touch Location).
When you choose Use Initial Touch Location, iPod touch uses the location of your first tap—when you tap an app on the Home screen, for example. Choose Use Final Touch Location, and iPod touch registers the tap where you lift your finger. iPod touch responds to a tap when you lift your finger within a certain period of time. Use the Gesture Delay plus and minus buttons to adjust the timing. Your device can respond to other gestures, such as drags, if you wait longer than the gesture delay.
Choose how iPod touch responds when you press and hold the Home button. Go to Settings > General > Accessibility > Home Button, then choose Siri, Voice Control, or Off.
